Wrist exerciser

ABSTRACT

An exercising device for the hands, wrist and forearms including an elongated bar having an enlarged flange integral with one end thereof. An enlarged rotatable member is carried at right angles to the bar in frictional contact with the flange. A friction producing member is carried between the flange and the rotatable member resisting forces exerted by the hands tending to turn the bar with respect to the rotatable member. An adjustable spring is provided for varying the frictional contact between the flange and the rotatable member.

wrus'r EXERCISER This invention relates to an improved wrist exerciserespecially adapted to provide exercise to strengthen the wrist forplaying golf and the like, where one of the hands is to be moved atright angles to the palm and forearm, whereas, the other hand is to bemoved in the plane of the extended palm and in the plane of the forearm.

Heretofore, wrist exercising devices have been supplied wherein bothwrists are exercised in the plane of the palm and forearm, such asillustrated in U.S. Pat. No. 684,117. Such devices contemplated two handpieces with a friction producing means therebetween. A similar device isillustrated in US. Pat. No. 3,396,967 except that both wrists areexercised by turning in a direction at right angles to the palm and theforearm, the latter device comprising two bar portions joined by afriction and force producing member.

The present invention contemplates the use of a bar for accommodatingthe palm of one hand, carrying an enlarged member at right angles to thebar for accommodating the palm of the other hand with a frictionproducing means therebetween resisting relative movement between thesemembers.

Accordingly, it is an important object of this invention to provide anexerciser capable of exercising the wrist of one hand in one directionand the wrist of the other hand at right angles thereto, such as wouldbe the case with the golf shot, baseball and others. The grip of bothhands is also exercised so as to be improved.

Another important object of the invention is to provide a hand, wristand arm exerciser which may be easily constructed for economical use,and capable of exercising the wrist in the same plane as the wrist orpalm. Either hand may be exercised in this fashion by changing hands onthe device.

The construction designed to carry out the invention will be hereinafterdescribed, together with other features thereof.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawingforming a part thereof, wherein an example of the invention is shown andwherein:

FIG. 1 is a perspective view illustrating a wrist exerciser constructedin accordance with the present invention in the hands of a user,

FIG. 2 is a longitudinal sectional elevation of the wrist exerciser, and

FIG. 3 is a transverse sectional elevation taken on the line 3--3 inFIG. 2.

The drawing illustrates a wrist exerciser having an elongated bar Aadapted to receive a users clenched hand thereabout with a first palmextending along the longitudinal axis of the bar. An enlarged member Bis carried adjacent an end of the bar at right angles thereto adapted toreceive a users other hand with a second palm at right angles to saidfirst palm, and with the fingers adjacent the periphery thereof. Afriction producing means C carried between the bar and the enlargedmember opposing a force exerted by the hands tending to turn the barwith respect to the member. Thus, the wrist of the clenched hand isexercised in a direction at right angles to the first palm, while thewrist of the other hand is exercised in the plane of the second palmmuch as would be the case in executing a golf shot and the like. I

The elongated bar A includes a tubular sleeve having an upper rim 1 land a lower flange l2 integral therewith. The tubular member 10, also,has a seat portion 13 for accommodating the compression spring 14 on oneend. The spring is confined by a cap 15, which has a depending flange 16which is notched as at 17a to receive projections 18 carried by theupper rim 11. The cap 15 carries a longitudinal shaft 17 which isthreadably secured as at 18 to an internal bore within a sleeve 19. Thesleeve 19 is secured to a disc 20 carried integrally at right anglesthereto. The sleeve 19 is received within a restricted lower portion 21of the sleeve 10. Preferably, the restricted lower portion 21 has anopening 21a, rectangular or otherwise, therein to receivecorrespondingrsileeve 19 to prevent rotation therebetween.

e enlarged member B 18 a wheel having a nm 22 carried by a flat web 23.The web of the disc 20 and the web 23 carry leather portions 20a and23a, respectively, and these and associated parts form the frictionproducing means C for receiving the enlarged member B.

It will be observed that the bar consists essentially of the roundtubular element 10, and that the wheel has a rim carried by a flat webwhich is confined by the friction producing means C, which includes apair of spaced spring biased discs confining the flat web 23therebetween and resiliently bearing thereagainst. The compressionspring 14 urges the shaft 17 upwardly resiliently confining the web 23between the disc 20 and the flange 12. The leather portions 20a and 23atend to produce a friction force tending to resist forces which wouldresult in rotation between the rod and the wheel. The cap 15 is carriedfixedly by the shaft 17. By turning the cap against the notches 17a thethreaded end of the shaft is turned to go further into or out of thesleeve 19. Thus, the spring 14 is shortened or lengthened to increase ordecrease the friction between the wheel and the shaft.

While a preferred embodiment of the invention has been described usingspecific terms, such description is for illustrative purposes only, andit is to be understood that changes and variations may be made withoutdeparting from the spirit or scope of the following claims:

What is claimed is:

1. A wrist exerciser comprising, an elongated bar adapted to receive ausers clenched hand thereabout with a first palm extending along thelongitudinal axis of the bar, an enlarged member carried adjacent an endof the bar at right angles thereto adapted to receive a users other handwith a second palm at right angles to said first palm and with thefingers adjacent the periphery thereof, resilient means for yieldinglybiasing at least one of said bar and enlarged member toward the other,and friction producing means carried between the bar and the enlargedmember and actuated by said resilient means to oppose a force exerted bythe hands tending to turn the bar with respect to the member, wherebythe wrist of the clenched hand is exercised in a direction at rightangles to the first palm while the wrist of the other hand is exercisedin the plane of the second palm much as would be the case in executing agolf shot and the like.

2. The wrist exerciser set forth in claim 1, wherein said bar has around cross-section, wherein said enlarged member is a wheel having arim carried by a flat web, and wherein said friction producing meansincludes a pair of spaced spring biased discs confining the flat webtherebetween and resiliently bearing thereagainst.

3. The wrist exerciser set forth in claim 2, further comprising: meansfor increasing or decreasing the biasing force of said resilient means,whereby the opposition to turning may be adjusted.

1. A wrist exerciser comprising, an elongated bar adapted to receive auser''s clenched hand thereabout with a first palm extending along thelongitudinal axis of the bar, an enlarged member carried adjacent an endof the bar at right angles thereto adapted to receive a user''s otherhand with a second palm at right angles to said first palm and with thefingers adjacent the periphery thereof, resilient means for yieldinglybiasing at least one of said bar and enlarged member toward the other,and friction producing means carried between the bar and the enlargedmember and actuated by said resilient means to oppose a force exerted bythe hands tending to turn the bar with respect to the member, wherebythe wrist of the clenched hand is exercised in a direction at rightangles to the first palm while the wrist of the other hand is exercisedin the plane of the second palm much as would be the case in executing agolf shot and the like.
 2. The wrist exerciser set forth in claim 1,wherein said bar has a round cross-section, wherein said enlarged memberis a wheel having a rim carried by a flat web, and wherein said frictionproducing means includes a pair of spaced spring biased discs confiningthe flat web therebetween and resiliently bearing thereagainst.
